Application filed January 23, 1907. Serial No. 353,607.

' To a, w/mm, it Worry concern:

Hamilton, State of Ohio, have invented Be it known that I, HENRY E. DECKE- BACII, a citizen of the United States of Amer- B, is controlled by a float-valve, g, and whose outer end leads to a waste pipe, 9.

' Within the bottom of receptacle, B, a so ice, and a resident of Cincinnati, county of i lution,preferablyof calcium chlorid is placed,

tain new and useful Improvements in Ap paratus for Purifying, Cooling, and Drying Air, of which the following is a specification.

It is the purpose of my invention to provide a means forsupplying air in a cooled,

. dried andpurifled state to a room, which is especially adapted for use in rooms wherein fresh meat is hung. In these rooms it has been observed that there is a. great deal of moisture arising from the meats, especially where they are fresh, due to the presence of animal heat therein. In these rooms, where the cooling is effected by cooling fluids passed through pipes, this moisture becomes condensed and frozen-upon the pipes frequently to a great thickness.

With my invention the air is withdrawn from these rooms, and purified, cooled, dried, and then returned to them. During this process the air likewise in my apparatus is placed in a state such that its action upon the fresh meats is to render them less liable to infection.

In the drawing I have illustrated a vertical sectional view through my apparatus and through a room supplied therewlth, the room being shown partly cut away and the ends being brought together to economize space.

At one end of the room, A, is located a cylindrical rece tacle, B, upon whose bottom is situated a coi of pipe, C. Coil, C, is in'the form of a pyramidal housing, the coils being closelywound so as to leave narrow interstices between the coils. The upper and lower end of the coil, 0, extend through the walls of the receptacle, B, andth'rou h them a coolin fluid, such as ammonia, is ected. Vertically through the center of coil, 0, extends a pipe, D, whose upper end is connected to a pump, (1, into which a pipe, D, leads "from the upper part of the room,-A. The lower end of pipe, D, where it opens into the bottom of receptacle, B, has a conical screen,d

Above coil, C, are located two perforated shelves, E and E. Above shelf, E, an air pipe, F, leads to the bottom of the room, A,-

at the opposite end from that in which the receptacle, B, is situated.

Below shelf, E, is a discharge pipe, G, the opening of whose end within the receptacle,

cerso as to cover the coil, C. Between the shelves, E, and E, crystals of calcium chlo-i rid are placed. The calcium chlorid in the liquid in the bottom of the receptacle has the effect of keeping the liquid from freezing, although the ammonia passing through coil, C, may lower the temperature below that of the freezing point of water.

Pump, d, draws the air from the top of the room and forces it down through pipe, D,

from which it is discharged at the bottom of the receptacle, B. I Screen, d disperses the air somewhat as it arises throughout the housing formed by the coil, C. The air then passes through the interstices between the coils, being thereby brought into intimate contact with the coils containing the cooling fluid and is therebylowered greatlyin its temerature. The housing formed by the coil likewise has the effect of reducing or dispersing the force of the upward rise of the air through the fluid, so that the bubbling at the surface of the fluid is lessened. In assing through the fluid, the air is both coo ed and purified. When it leaves the fluid, it has a certain amount of moisture. through the perforations in the plate, E, which has the effect of dispersin the air through all arts of the crystals 0 calcium chlorid held etween the two shelves. In its passage through the crystals ofcalcium chlorid the air is dried, and likewise further purified, passing from the receptacle, B, by pipe, F, to the o posite end of the room in a co d, purified an dry state.

The moisture taken u by the calcium chlorid between shelves, and E, dissolves some of the salt .and this concentrated solu- It then rises tion falls through the perforations in the shelf, E, into the solution held in the rece tacle, B. The impurities in the solution, B, rise to the to thereof. The solution falling from the she f, E, causes the fluid to rise in the receptacle, B, and to open the floatvalve, g, the impurities upon the surface of the fluid then passing through the valve, G,

to the drain pipe, g.

What Iclaim is: I

1. In an air cooling and purifying a aratus the combination of a receptacle hol iling a solution of a salt which has the property of absorbing moisture from the air, a means for TIO cooling the solution, a perforatedshelf located in the receptacle and holding the salt above the'solution thereof, a pipe leading in to the bottom of the receptacle and connected to the pump, the pun p, and a second pipe leading from the top of the room into the pump. L i

2. In an air cooling and purifying ap )aratus the combination of a receptacle holding the solution of a salt which has the property of absorbing moisture from the air, a' pipe carrying a cooling liquid and coiled so as to leave interstices between the coils and forming a housing situated upon the bottom of i 20 In an air cooling and purifying a-ppara the receptacle, an air pipe leading into the hous;ng formed by the COllS, a pump conthe solution;

ing the solution, a erforated shelf located in.

the receptacle and olding the salt of calcium chlorid-above the solution, an air pump, and

a pipe leading from the pump in to the bottom of the receptacle.

4. In an air coolin and purifying a araa hofiii tus the combination of a receptacle ng a solution of calcium chlorid, a means of cool- 'ing the solution, a perforated shelf in the rece tacle holding calcium chlorid above the so ution thereof, a pump, an air pipe leading from the pump in to the bottom of the receptacle and a drain pipe located in the receptacle below the erforated shelf.
